Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551724, here are decompositions:

7 + 551717 = 551724
11 + 551713 = 551724
31 + 551693 = 551724
53 + 551671 = 551724
71 + 551653 = 551724
73 + 551651 = 551724
127 + 551597 = 551724
137 + 551587 = 551724

Showing the first eight; more decompositions exist.
